[Bug target/91602] GCC fails to build for riscv in a combined tree due to misconfigured leb128 support

Yeah, this is a bit a rat hole.  Of course there's nothing about
RISC-V that precludes the use of the leb128 data formats.  We fib that
they aren't supported to prevent the DWARF emitters from subtracting
label addresses at assembly time.  RISC-V linker relaxations foil the
assumption that those differences won't change after linking.
